Warning: I ran 50 parts with the wrong tool offset and didn't notice until QC flagged it

Tbh I was so focused on hitting cycle time that I completely forgot to check my offsets after a tool change. QC caught it on the 50th part when the bore came out 0.002 oversize, and now I triple check every single setup. Anyone else had a similar brain fart that taught you a hard lesson?

50 parts with a .002 oversize bore? I gotta be honest, that doesn't sound like a brain fart to me. You ran a whole batch and didn't catch that the tool was off. A brain fart is forgetting to hit the coolant button once. This is more like a system failure on your part. I mean, how do you not check the first part after a tool change? Thats basic stuff. The cycle time focus excuse kinda falls flat when you're making scrap.

Elizabeth reminds me of my old boss who scraped 200 parts by typing 2.0 instead of 20.0.

Whoa, hold on now. With respect, I think you're being a bit harsh on Elizabeth. A .002 oversize bore on a single operation isn't something you'd necessarily catch just looking at the part, especially if the tool was cutting fine for the first few pieces. Sometimes those little decimal slips happen and the first sign of trouble isn't until the bore gauge tells you, which could be after a whole batch.
